Many of the European powers had entered into alliances requiring them to defend each other.
The systems of alliances and military plans which were put in place before World War I presupposed a major war between the countries which were tied together with alliances. Because the Triple Entente had Britain, France and Russia as allies, Germany thought if a war began it would need to fight on two fronts -- west and east. So German Field Marshall Alfred von Schlieffen drew up war plans that said attack France first, quickly, and then hold that territory while deploying forces to contend with Russia in the east.
So then here's how it happened. When an Austrian prince and his wife were assassinated in Serbia, the Austrian Empire threatened the nation of Serbia with retaliatory action (even though the assassination was carried out by a terrorist group, not the Serbian government). Russia responded to Austria's threat, because Russia was bound to protect its Slavic ally, Serbia. Germany responded to the mobilization of Russian troops, and when Germany declared war on Russia in 1914, they implemented the Schlieffen Plan and went on attack vs. France. That pulled France and Britain into the war immediately as well, and the war spread and became a global conflict.

Answer:
Let´s try to put it simple. The separation of powers system establishes the competencies, the actions, the prerrogatives, the domains where each branch of government can exercise their powers, different from those of other branches. For example, taxes are set by Congress, and the presidency´s job is to collect them. Interpretation of laws corresponds to the judiciary, not to the president nor Congress.
On the other hand, checks and balances create counterweights to a possible abuse of power by one branch, giving branches of government legal instruments to check, to restrain the actions of another branch. For example: the US administration negotiates and sign foreign treaties, but the Senate must ratify them. Sometimes, it has refused to approve a treaty as when the Senate did not ratify the Treaty of Versailles in 1919 as requested by president Woodrow Wilson.
